Estradiol benzoate/estradiol dienanthate/testosterone enanthate benzilic acid hydrazone (EB/EDE/TEBH), sold under the brand names Climacteron, Lactimex, Lactostat, and Amenose, is an injectable combination medication of estradiol benzoate (EB), an estrogen, estradiol dienanthate (EDE), an estrogen, and testosterone enanthate benzilic acid hydrazone (TEBH), an androgen/anabolic steroid, which is used in menopausal hormone therapy for peri- and postmenopausal women and to suppress lactation in postpartum women.[1][2][3][4][5][6][7] Clinical studies have assessed this formulation.[8][9][10][11][12][13][14][15][16][17][18][19][1]

Climacteron and Amenose contained 1.0 mg EB, 7.5 mg EDE, and 150 mg TEBH (69 mg free testosterone) and was used to treat menopausal symptoms.[20][17][21] They were administered by intramuscular injection typically once every 6 weeks but with a range of every 4 to 8 weeks or less frequently.[20] Climacteron was marketed in Canada in 1961 but was withdrawn in this country in October 2005 due to risk of endometrial hyperplasia and cancer from unopposed estrogen exposure (i.e., no concomitant progestogen) as well as induction of supraphysiological testosterone levels.[1][22][23]

Lactimex and Lactostat contained 6 mg EB, 15 mg EDE, and 300 mg TEBH in 2 mL of corn oil and were used to suppress lactation.[2][3][24][25] They were administered as a single intramuscular injection after childbirth or during breastfeeding.[2] They were previously available in Germany and Canada.[2][25]

Estradiol and testosterone levels following a single intramuscular injection of EB/EDE/TEBH versus 10 mg estradiol valerate have been studied over 28 days.[14][16]

Notes and sources Notes: All aqueous suspensions are of microcrystalline particle size. Estradiol production during the menstrual cycle is 30–640 µg/d (6.4–8.6 mg total per month or cycle). The vaginal epithelium maturation dosage of estradiol benzoate or estradiol valerate has been reported as 5 to 7 mg/week. An effective ovulation-inhibiting dose of estradiol undecylate is 20–30 mg/month. Sources: See template.

This product is sold in Germany under the name Lactimex and has been clinically examined by us.] [...] Of 1200 postpartum patients one quarter stopped breast feeding for a variety of reasons and received an injection of Lactimex (Protina: Benzil acid hydrazon-testosteron-oenanthat 300 mg, Oestradiol-di-oenanthat 15 mg and Oestradiol-benzoate 6 mg in 1.0 ml of oil). In 76% of cases one injection was sufficient and the remaining 24% required a second injection. A second injection was required rarer if the first injection had been longer after delivery. A higher dosage of Lactimex was not necessary in cases with a preceding medical induction with intraveinous Oxytocin (Orasthin). Mothers who had been treated postpartum with methylergobasin did not as often require a second injection. No localized or generalized adverse reaction to the drug was noticed.
